STEM WINDING AND SETTING WATCH.

EPEGIEICATIUN forming part of Letters Patent No. 356,134, dated January18, 1887.

Application filed February 19, 1886. Serial No. 192,583. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE F. Johnson, a

citizen of the United States, residing at Aurora, in the county of Kaneand State of Illinois, have invented certain new and useful Improvementsin Stein-finding and Storm Setting \Vatches, of which the following is afull, clear, andconcise description.

This invention relates to the stem winding and setting devices ofwatches in which the winding and setting mechanism is changed from thewinding to the setting engagement by pulling out the stem or pendant ofthe watch a limited distance; and it consists in a novel constructionand combination of parts, especially of the pendent plug or key, and theparts in immediate connection therewith, by which motion is communicatedto a swinging yoke similar to the yoke commonly used in stem-windingwatches, causing it to be swung at will from winding to setting positionand there firmly held.

1 am aware that other devices arein use for the accomplishment of thesame purpose, but claim that my invention combines more advantages thanhave heretofore been secured by any single method of construction, amongwhich are adaptability to ordinary stenrwinding cases, either hunting oropen face, an unconstrained condition of the parts in the normal orwinding position, ease of removing the pendantplug, and reduced.liability to derangement from wear and consequent lost mo tion.

Reference is to be had. to the accompanying drawings, forming part ofthis specification in which similar letters indicate corresponding partsin the several. figures.

Figure 1 represents a face view,upon an enlarged scale,of thepillar-plate of a stem winding and setting watch, to which the windingand setting mechanism is attached and having my inventionapplied,showing the device in position for setting the watch, also showing thependant plug or key with crownpiece attached, said plug or key beingpulled outward to its limit. Fig. 2 is a similar view showing the partsin position for winding, the key being pushed inward to its limit. Fig.8

is a sectional View, on the linen: x of Fig. 2,

vertically through pillar and top plates. Fig. 4 is a vertical sectionof Fig. 2 on the center line of thependant, showing bevel-pinion andpendant-plug, also bridges that hold bevel pinion to plate.

A is the pillar-plate of the watcl1,and B the swinging yoke arranged toswing concentrically with the large spur and bevel geared wheel 0. Thiswheel is actuated by a bevelpinion and the pendant of the watch, as iscustomary in stem-winding watches.

The yoke B carries at either end the wheels D, E, and F, one of which,D, meshes into the ratchet I and effects the winding. The others, E andF, connect the crown-Wheel G with the cannon-pinion J and effect thesetting of the watch-hands.

G is a lockingbar pivoted at c and connected in any suitable way withthe jointed and pivoted levers L and M, which embrace the pendantplug K,and which are held in a closed position in contact with said plug by theforce of the spring ll: acting through the locking'bar G and theconnection (I. The pendant-plug K, in addition to its square, by whichit performs its customary function of actuating the bevel-pinion, has acylindrical portion, turned to different diameters, connected by abeveled or longitudinally-rounded portion.

The action of the device is as follows: In the normal or windingposition of the parts the pivoted levers L and M embrace the smallercylindrical portion of the pendant-plug, as shown in Fig. 4:, while theyoke stands in the winding position, as shown in Fig. 2, being held inits engagement with the ratchet 1 by the force of the spring H actingthrough the locking'bar G. to setting position, the pendantplug ispulled outward, and by means of its angle the pivoted levers are openedto embrace its larger portion, carrying, by means of their connections,the locking-bar G- to the position shown in Fig. 1, in which position,by rotating the pendant,inotion is com munieated to the watch hands forthe purpose of setting. When the pendant is pushed in, the parts, by theforce \Vheu it is desired to change,

of the spring H, return to the winding posiplate or attached piece,andarranged to 01)- tion, as shown in Fig. 2. crate substantially as andfor the purpose Having thus described myinvention, I claim shown anddescribed.

as new and desire to secure by. Letters Patent GEORGE F. JOHNSON. 5 Incombination with an endwise-niovable XVitnesses:
